The Poverty of Empiricism Informing Science Journal Volume 8, 2005 The Poverty of Empiricism Jens Mende University of the Witwatersrand, Johannesburg, South Africa. [email protected] Abstract Many researchers – and their advisors on research method – adopt a doctrine called empiricism, which claims that researchers may only use empirical methods. This restrictive doctrine impover- ishes any academic discipline where it is dominant. The main reason is that a discipline only qualifies for the status of a science after it has progressed beyond empirical generalisations to ex- planatory theories; but although empirical methods are useful for discovering the former, they are inherently useless for creating the latter. So the empiricist doctrine retards scientific progress. Re- searchers should be aware of this danger, and research methodologists should attempt to counter it. Keywords: Empiricism, Positivism, Research Methodology, research methods, empirical re- search, theoretical research Introduction There is a world of difference between the terms ‘empirical’ and ‘empiricism’. The term ‘empiri- cal’ refers to a battery of very useful research methods. The term ‘empiricism’ refers to a restric- tive methodological doctrine which claims that researchers may only use empirical methods. The purpose of this paper is not to disparage empirical research methods, but to warn readers that the empiricist doctrine impoverishes any discipline where it is deeply entrenched (Gower, 1997, p10), and to suggest some avenues of counteraction. The subsequent sections explain why the empiricist doctrine impoverishes research. The first sec- tion shows that researchers need knowledge of various kinds of research processes and knowl- edge products, and that this knowledge is distributed over three academic disciplines: Philosophy of Science, History of Science and Research Methodology. The next three sections examine the origin and current status of the empiricist doctrine in the Philosophy of Science, and the debilitat- ing effect of empiricism on research process and product knowledge in the History of Science and in Research Methodology. The last section calls for counter-action in the form of meta-research aimed at identifying non-empirical research processes and knowledge products that could be mentioned in those three disciplines – Material published as part of this journal, either online or in print, especially in Research Methodology. is copyrighted by the publisher of Informing Science.

Methodological Knowledge Research is a process of producing new knowledge. So it is a productive process similar to the productive processes of manufacturing cars, computers, software, etc. Some useful insights emerge by analysing the other productive processes and then comparing them with the research process. All productive processes require productive knowledge. For example: · in order to produce cars, people need knowledge of car production; · in order to produce computers, they need knowledge of computer production; · in order to produce software, they need knowledge of software production. Productive knowledge consists of process knowledge as well as product knowledge (see Mende, 2000 for more detail). When manufacturers establish a new factory, they have to decide what the factory is to produce, and how the factory will produce it. So they need to know what kinds of manufactured products are needed, and what kinds of processes can be used to produce them. For example, when Henry Ford decided to produce motor cars, he had to know that people need cars, and that cars can be produced on a production line. Similarly, when researchers embark on a research project, they have to decide what knowledge product to produce and how to produce it. So they too need to know what kinds of knowledge products are required and what kinds of research processes can be used (Kantorovich, 1993, p11; Singleton, Straits & Straits, 1993, p18). For example, when Ohm embarked on his famous re- search project to find the empirical law of electric current variation with voltage, he had to be aware that people need empirical laws, and that empirical laws can be produced by means of in- ductive research processes. Similarly, when Darwin embarked on his famous research project on the theory of evolution, he had to be aware that people need theories, and that theories can be es- tablished by means of deductive research processes. Therefore, by analogy with manufacturing management, researchers need knowledge of different types of research processes and knowledge products. Since this is knowledge about knowledge, it may be called ‘meta-knowledge’. For convenience of access, all our meta-knowledge should be concentrated in a single academic discipline. But that is not so. Instead, our meta-knowledge is scattered across three different disciplines, namely History of Science, Philosophy of Science and Research Methodology. History of Science is an old-established discipline, which began with the ancient Greeks (Lloyd, 1973). Today, it describes many of the knowledge products that were discovered by real-life re- searchers, and also some of the research processes that those researchers actually used. Philosophy of Science is another old-established discipline, which also began with the ancient Greeks. Today, it mainly analyses the validity of existing knowledge products, but occasionally considers the research processes too. Unfortunately, many publications in Philosophy of Science make scant reference to History of Science, and most of them ignore Research Methodology alto- gether. Research Methodology is an emerging new discipline that aims to unify many of the methodo- logical principles found in the various sciences and proto-sciences. During the latter half of the 20th century, specialised methodological branches have emerged in many of those disciplines to focus on issues of method. For example, in the natural sciences there are textbooks on experimen- 190 Mende tal techniques of physics and chemistry, and on microscope techniques in biology and geology (Furniss, Hannaford, Smith, & Tatchell, 1989; Heinrich, 1965; Sanderson, 1994). In the social proto-sciences there are textbooks on experimental psychology, sociological method, anthropo- logical research, educational research and business research (Cassell & Symon, 1994; Christen- sen, 1980; Cole, 1980; Foskett, 1965; Pelto & Pelto, 1978; Zikmund, 2003). Yet certain methods are common to many of these disciplines. “The research procedures of most academic disciplines follow the dictates of the scientific method … In many instances, only the tools of research are different. The biologist gathers data by way of the microscope, the sociologist does likewise through a questionnaire. From there on the basic procedure of each is the same: to process the data, interpret them, and reach a conclusion based on factual evidence.” (Leedy, 1989, p. vii). The new discipline of Research Methodology identifies and explains these common research pro- cedures. Unfortunately, most publications in Research Metholology make scant reference to Phi- losophy of Science and History of Science. The three disciplines are subject to the force of fashion (Lovelock, 1995, p. 204; Nagel, 1961, p. 115; Sperber, 1990). This force arises in any social group, including a community of scholars. A scholar in an academic discipline is subject to research fashions in the same way as anyone else is subject to clothing fashions, motorcar fashions, food fashions, etc. The next three sections focus on the empiricist fashion. It originated in the Philosophy of Science, where it is now dismissed with contempt; but has spread to History of Science, where it is still mildly influential, and to Re- search Methodology, where it remains dangerously dominant. Philosophy of Science The precursor of empiricism was a philosophical doctrine called positivism. This was a doctrine of neglect. It called for neglect of a particular class of knowledge products, namely theories, and especially those theories that involve un-observable first causes (Oldroyd, 1986, p. 169). Positiv- ism originated in the 18th century, when Berkeley denied the reality of theoretical objects such as the Newtonian forces of mechanics (Losee, 1993, p. 168). Positivism was subsequently dissemi- nated by two influential 19th century philosopher-scientists: the sociologist Comte, who asserted that ‘science must study only the laws of phenomena’, and the physicist Mach, who attempted

TITLE On Becoming a Pragmatic Researcher: The Importance of Combining Quantitative and Qualitative Research Methodologies. PUB DATE 2003-11-00 NOTE 25p.; Paper presented at the Annual Meeting of the Mid-South Educational Research Association (Biloxi, MS, November 5-7, 2003). PUB TYPE Reports Descriptive (141) Speeches/Meeting Papers (150) EDRS PRICE EDRS Price MF01/PCO2 Plus Postage. DESCRIPTORS *Pragmatics; *Qualitative Research; *Research Methodology; *Researchers ABSTRACT The last 100 years have witnessed a fervent debate in the United States about quantitative and qualitative research paradigms. Unfortunately, this has led to a great divide between quantitative and qualitative researchers, who often view themselves in competition with each other. Clearly, this polarization has promoted purists, i.e., researchers who restrict themselves exclusively to either quantitative or qualitative research methods. Mono-method research is the biggest threat to the advancement of the social sciences. As long as researchers stay polarized in research they cannot expect stakeholders who rely on their research findings to take their work seriously. The purpose of this paper is to explore how the debate between quantitative and qualitative is divisive, and thus counterproductive for advancing the social and behavioral science field. This paper advocates that all graduate students learn to use and appreciate both quantitative and qualitative research. In so doing, students will develop into what is termed "pragmatic researchers."

  • The Anti-Essentialism Paper
    The New Pragmatism, Anti-essentialism, and What is Universal: It’s The Situation All The Way Down C. F. Abel Stephen F. Austin State University [email protected] The New Pragmatism, Anti-essentialism, and What is Universal: It’s The Situation All The Way Down C. F. Abel Stephen F. Austin State University [email protected] A well-known scientist once gave a public lecture on astronomy. He described how the Earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At the end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man," said the old lady. "But it's turtles all the way down!" Introduction “New Pragmatism” attacks the very foundation of pragmatic thought by denying that we may ever have any definitive experience. As what we are experiencing is up for grabs, we can never know any situation that we may encounter, and we are left to ground both our knowledge and our values in our language games alone. This paper argues that this set of claims is founded on two errors, one regarding the nature of language games and the other regarding the nature of deconstruction. The “Old Pragmatism,” by way of contrast, is non-essentialist but not anti- essentialist, and it resolves the problem of how we might know “the situation,” given the subjectivity of our observations and the contingencies of our language games, by suggesting that our experiences can be understood as existing in, and constituted by, the totality of their particular instances or modes at the time of inquiry.

  • The Historical Turn in the Philosophy of Science
    THE HISTORICAL TURN IN THE PHILOSOPHY OF SCIENCE 1 Developments in the History of Science The history of science has a long history. Aristotle’s scientific works are prefaced by historical account of those sciences, and this model persisted through medieval times until and including the rise of modern science in the era of the scientific revolution. Joseph Priestley, for example, entitled two of his books of pioneering research The History and Present State of Electricity and The History and Present State of Discov- eries Relating to Vision, Light, and Colours. For many such early modern authors the history of science serves as a propaedeutic. William Whewell’s A History of the Induc- tive Sciences (1857) is regarded as the first genuinely modern work of the history of science. Even so, Whewell’s scholarship has an extra-historical purpose, which was to furnish the materials against which a satisfactory philosophy of science could be con- structed. While Whewell rejected a Leibnizian logic of discovery, he did nonetheless believe that general principles of scientific inference could be uncovered by careful consideration of the history of scientific research. Whewell’s approach was followed by several early positivists, notably, Mach, Ostwald, and Duhem. Nonetheless, as positivism developed philosophically it also became more ahis- torical. Carnap’s programme of a priori inductive logic was premised on a distinction between a context of discovery and a context of justification. The former concerned the process of coming up with an hypothesis, whereas the latter concerns its justification relative to the evidence. The former would be the province of psychology, although it may depend so much on details of individual biography that few general principles may be derived even a posteriori.

  • Evaluating Empirical Research
    EVALUATING EMPIRICAL RESEARCH A NTIOCH It is important to maintain an objective and respectful tone as you evaluate others’ empirical studies. Keep in mind that study limitations are often a result of the epistemological limitations of real life research situations rather than the laziness or ignorance of the researchers. It’s U NIVERSITY NIVERSITY normal and expected for empirical studies to have limitations. Having said that, it’s part of your job as a critical reader and a smart researcher to provide a fair assessment of research done on your topic. B.A. Maher’s guidelines (as cited in Cone and Foster, 2008, pp 104- V 106) are useful in thinking of others’ studies, as well as for writing up your IRTIUAL own study. Here are the recommended questions to consider as you read each section of an article. As you think of other questions that are particularly W important to your topic, add them to the list. RITING Introduction Does the introduction provide a strong rationale for why the study is C ENTER needed? Are research questions and hypotheses clearly articulated? (Note that research questions are often presented implicitly within a description of the purpose of the study.) Method Is the method described so that replication is possible without further information Participants o Are subject recruitment and selection methods described? o Were participants randomly selected? Are there any probable biases in sampling? A NTIOCH o Is the sample appropriate in terms of the population to which the researchers wished to generalize? o Are characteristics of the sample described adequately?

(Suggestion: Look at these questions before you first read the selections.) What is Science? Science is the systematic study of the physical world. Qualification: “Science” = “Natural Science” Science is based upon observations of that world. Science is empirical and progressive. It involves the formulation and testing of hypotheses. Science attempts to explain natural phenomena. Goals and Objectives To gather information through observation and experiment To organize and systematize that knowledge To infer the the “laws of nature” which govern natural events The Domain of Science Physical Reality Science deals only with physical (“real”) objects and events, those which are either directly observable or whose existence can be inferred indirectly from observations. Observations must generally be reproducible (“witnessable”) to be considered real. (cf. ghosts, hallucinations, beliefs, ....) Note: Single (past) non-reproducible events or observations can sometimes be accepted as “real” if supported by a suitably large body of evidence. Factual Knowledge (“Data”) Information whose accuracy has been confirmed again and again by repeated observation or experiment. This “Information” can include fundamental principles, testable hypotheses, as well as directly observed events, processes and connections.

DESCRIPTORS *College Curriculum; *Communication (Thought Transfer); Comparative Analysis; *Educational Change; Educational Research; Foreign Countries; Global Approach; Higher Education; *International Education IDENTIFIERS *Internationalism ABSTRACT This paper surveys the current situation of internationalism among the various nation states by a comparative analysis, as matrix, to promulgate the internationalizing process, as a worthwhile goal, within and without the college and university curricula; the theoretical influence and contributions of scholars in communication, international education, and political-economy, moreover, become allies toward this endeavor. The paper calls for the promulgation of a new and more effective educational paradigm; in this respect, helping the movement toward the creation of new and better schools for the next millennium. The paper profiles "poorer nations" and "richer nations" and then views the United States, with its enormous wealth, leading technology, vast educational infrastructure, and its respect for democratic principles, as an agent with agencies that can effect positive consequences to ameliorating the status quo. The paper presents two hypotheses: the malaise of the current educational paradigm is real, and the "abertura" (opening) toward a better paradigmatic, educational pathway is advisable and feasible.
